To all whom it` may concern: Be. 't known that l, EDWIN M. ROSEN- BLUTH, of the city of Philadelphia andv Sta-tc y of Pennsylvania, have invented a certain new and useful Im rove'ment in Acetylenef Gas Generators, 1v iereof the following is. a specification, reference being had to the ac corpa'nying drawings.4

i Y generators wherein the Water chamber isA in 'superimposed relation 'to the 4carbid recep-` tacle and the Water gravitates to the carbid. Itis the object of my invention to provide such a enerator with means arranged to evenly distributethe water to the peripheryoil the carbid mass and. to terminate the sup vly of gas tothe burner contemporaneous y with the termination of the supply of water. l

The form. of my invention hereinafter described comprises a 'water receptacle having su porting means, a .carbid casing' removably secured in subjacent relation to'said vWater receptacle vand inclosing a carbid receptacle,.a dome shaped ca loosely iittedl within said receptacle, over-t e carbid, and a valve'having a' gas passage and a' Water passage, the latter passage being restricted and 'arrangedto direct Water onto said cap; lsaid vvalve g passage is closed the gas passage is contemporaneously opened to connect-- thegas chamber with the yatmosphere and permit the escape'of the surplus gas producedby t after generation."v V

M1. invention comprises the various novel features of .construction and arrangement hereinafter more definitely-specified.

In the accompanying drawings,l Figure I is a central vertical section of a generator constructed finaccordance `With'my invention, .taken on the line I, I, inFig. III. Fig.

II, isi-a side elevation of the vWater receptacle as seen from the left of I. Fig. III, is a plan view of said generator. Fig., IV, is a` side elevation of the' domed 'cap for the carbid receptacle. Fig. V,.is aside elevation of thek carbid receptacle. Fig. VI, is central ver` tical section 4of the valve taken on the'line VI, VI in Fig. I.` Fig. VII, is a central vertical. section of the vacuum relief. passage taken onthe I ine VII, VII in Fig.' Il II. Fig.

v VIII, is a fragmentary sectional view 'offa' modified form oli-ca for the carbid recep-y tac'le. Figs. IXjan X are centralvertical .sections of modified forms of ,condensera improvement relates to that 'class 4of l y13 of the wat-er receptacle 1. l

in Fig. I, the bottom Wall 13, extends slightly eing so arranged that when the water .upon which'- is secured the 'annular ring 8,

comprising the upwardly extending flange 10, arranged toengage the annular rubber gasket 11. Said gasket` 11, is conveniently seated Within the channeled ring 12,y which issecured'to/the underside of the bottom Wall As best shown beyond the channeled ring 12, and terminates in the depending flange 15, which conven-l ientlyj conceals the joint between said Water receptacle and carbid casing.

The carbid casing 5, is arranged to be secured t-o the Water receptacle 1, by the swing bolts 17, which are pivoted ,in the brackets 18, on said casing, and provided with wing- `nuts 19, in threaded engagement with their freel ends. Asbest'shown in Fig. III, t-he 'swing bolts 17, are` arranged to be received between the forks of thebifurcated brackets 20, which are carried by the Water receptacle v1, andagainst which the Wing-nuts 19 are arranged to bear, and by their-rotation tol hermetically close the joint between the water receptacle and carbid chamber. V

The carbidreceptacle 22, is conveniently suspended Within the carbid casing 5, and comprises the foraininous iioor 23 through which the ashes precipitate to the bottom of said carbid casing A5', the upper edge of said receptacle being provided with the ilange 25, arrangedfto engage the ring 8 whereby it issuppo'rted.y Said carbid receptacle 22, is provided With a removable dome shaped cap 26,' arranged to fit loosely therein, .and has an inwardlyextending rib 27, formed'by rolling a bead parallel with its lower" edge. As shown in Fig'. I, saidlower edge rests upon cured within the carbid casing 5, to uphold saidy cap 26,`against Vthe compression ofthe spiral spring 30,-,Which is lcarried thereby.

Said lvvaterv receptacle Iis provided 'with a 4valve 33, whose plug 34, comprises. a handle yiic '35,- exterior to said receptacle, whereby said I therein.

.ter onto the plug is rotated; a stop pin 36, larranged to limit its movement; and independent pas`j sages 37 and 38, forwater andy gas respectively. The water passage 37, includes a restricted water outlet, opening into the carbid receptacle 2 2,l and arranged to directthe wadome of the cap 26, from whence it trickles down in' a thin film, between the Iside'walls of saidcap and carbid receptacle,

through the annular passageway between theplunger and the walls of the aperture.

In order to facilitate the free fiow of the water from the water receptacle 1, when the valve is opened, a vacuum relief tube 42 extends from the gas chamber 43, into the inclosure 44, which is conveniently provided with the screw cap 45, and which communicates withthe interior of the water receptacle r 1; through thel aperture 46, in its top wall. Said watergrcce tacle 1, is provided with a .filler 47, throng which it ma be charged, andqsaid filler is normally close by the screw ca *48.y

he gas generated in the carbid rece tacle escapes into thecharnber 43 between t e receptacle 22 and the cap 26,"and is-conveyed therefrom through the `centrally disposed tube 50, extending through the Water receptacle, and comprising t e perforatedvx diaphragm 51. Said tube 50 terminates slightly above the upper wall of the water receptacle and is arranged to support the condenser 52, which Fis in threaded engagement withk the tube 50, and is rendered gas tight by thel gasket 53, Said condenser also conveniently-serves as a knob or handle by which the generator may be carried, and is provided with the-elbow nozzle 54, arranged to be co'nnected with a burner by a fiexible conduit (not shown) but which may be conveniently slipped oversaid nozzle. Said condenser is rovided with a tubular extension which ibr'ms a filter casing 55, depending within the tube '50, and comprising a perforated diaphra m 56, within the filter casing 55, in Whic is packed a quantity of carbld ashes V60, interposed between layers` of absorbent cotton 61 and 62, and arranged to arrest the entrained moisture carried by the gaswhich is filtered therethrough in its passage from the carbid receptacle, to the nozzle 54.

The bar 57 protects the mouth of the tube from being closed by the cap 26, which might be uplifted against the tension of the s ring 30, by the expansion of the carbid, ine osed The gas passage 38 which is controlled by the valve 33, is arranged to open communication betweenl the gaschamber 43, and the'atrnosphere when the valve plug 34 is turned to shut off the supply of water to the carbld, and thus affords a free outlet from the generator for any after generation of gas, .and consequently the flame is extinguished contemporaneousl of saidr valve, and is there trolled. A l

It may be noted -that although I have with the closing y positively conshown in Fig. I, brackets arranged to support the dome shaped cap 26, .other means for supporting. the cap maybe em loyed, as for instance as shown in Fig. VI I, the cap 65, is arranged to extend to the fioorof the carbid receptacle and is provided with deep notches 66, cut in its lower edges to permit the free passage of water into contact with the carbid contalned therein.

As shown inFig. IX, the condenser may I vbe included within the water receptacle 70,

and comprise .the bottom wall 71, which slopes downwardly to the 0as tube 72; the elbow nozzle 73, being in threaded engagement with the cap 74, which is in threaded gas tight relation with the threaded collar 75, in the top wall of the water receptacle 70. As shown in F'g. X, the cap 80, comprises the elbow nozzle 81, and a dependin tubular extension 82, embracing the ltering material 83. Said cap is provided with the shield 85, secured thereto in registry with its gas passa e Way to prevent the filtering material c ogging the 'l entrance of said passa e way.

do not desire to limit myself to the pre voise details of construction and arrangement hereinafter described, as it is obvious that Various modifications may be made therein without departing from the essential features of my invention, as defined in the following claims.
